I see that crappie floats are a popular item for keeping the bait off the bottom which is all well in good if I wanted to spend money, but like most people I prefer not to. My mom works at a Styrofoam plant and I can get pretty much anything you could imagine made out of Styrofoam for free. What size of cylinders should I ask for. I am thinking 1 inch diameter by 3 inches long. Does that sound about right? Also where can I get buckshot and parachute chord to make slinky weights? And about how heavy should I make them. I would think 3 oz.?
